IPC: H01S5/00
Filed: 1989-03-06
Abstract: PURPOSE:To obtain a phased array laser stably oscillated at a primary mode by cutting off an N+1st, mode and injecting gains between stripes. CONSTITUTION:A mode in an order higher than the number of stripes N, a not less than N+1st mode, is cut off, and structure in which currents are blocked is formed in stripe regions 12. The width of the stripes is brought to 3mum or less, and currents are injected into the inter-stripe regions 12. Consequently, since the N+1st mode is cut off, the rate of stripe-gain injection is reduced gradually, thus increasing the difference of the threshold gains of a primary mode and the N+1st mode. Accordingly, a phased array semiconductor laser device, which is oscillated at the primary mode and outgoing beams of which are simplified, can be acquired.
